Hi guys,
Got into my three hives yesterday. Hive 3 had twice as many bees as the other two. Also loads of surplus nectar and pollen. Very nice broodnest. Hives 1 and two had much smaller broodnest with reasonable amount of pollen in the pollen band around the broodnest but the honey band and surplus combs were empty.
My diagnosis was that these hives didn't have enough forager force to keep the nurse bees supplied. I put sugar syrup feeders on all for them as I didn't want to start robbing and I figured if hive 3 didn't need it they would just not use it.
Did I do Okay?
